Fix cpu checks for older Linux kernels

Older Linux kernels don't have the "guest" field in /proc/stat.  While
check-cpu.rb claimed to accommodate that, it didn't actually work all
the way through.  Fix that, and also fix cpu-pcnt-usage-metrics.rb,
which didn't know about this at all.
whitespace fix
Created check-service

Took the check-process script and added /svc to the task search.
This seemed like the easiest way to get searching working.

Tested and works as expected.

Move spec to separate file from class

will test whole repo. Second - just one file or if you will
provide pattern - you will get file matching tested.
